我正在尝试在处于监控模式的 wlan1mon 设备上运行 ISC DHCP。但我收到错误：

答案1
当设备处于监控模式时，仅“嗅探”流量，不发送任何内容。因此无法发送dhcp报价，也dhcp无法使用此接口。
监控模式或 RFMON（射频监控）模式允许带有无线网络接口控制器 (WNIC) 的计算机监控从无线网络接收的所有流量。与同样用于数据包嗅探的混杂模式不同，监控模式允许捕获数据包而无需先与接入点或临时网络关联。监控模式仅适用于无线网络，而混杂模式可用于有线和无线网络。监控模式是 802.11 无线网卡可以运行的六种模式之一：主模式（充当接入点）、托管模式（客户端，也称为站点）、临时模式、网状模式、中继器模式和监控模式。
